Text not available

When I open a previously saved file I am plagued with the error "The text 'BDB' is not currently available to Accordance." The file will not open and BDB Complete is in my library. How can I fix this without deleting each file and starting all over again?

The problem is that your saved file was trying to find BDB, and it seems like you now removed BDB from your library and replaced it with BDB Complete. The easiest way to solve this is to re-add BDB to your library (it may still be in your Tools folder), then open your saved session and change the instances of BDB to BDB Complete, then resave the session.
